Figure 150: Bit display with overlaid static text
Screen 3
Screen 3 illustrates the possible uses of the Visibility tab for
the
bit display. In this screen a bit display element has been
enlarged to the full size of the screen. It is activated via the
Boolean
operand
Q1, with a make contact bit logic so that the
bit display element takes on the state of the output Q1 (on/off).
The bit display is made invisible via the Boolean
operand
Q3.
A make contact bit logic is also used here so that invisibility is
activated for as long as Q3 in the On state. When the Reset
pulse is present, only the frame of the bitmap is visible (state
of the bitmap is “off”, bitmap is visible). The display is overlaid
partly with static text.

Screen 4
Screen 4 illustrates the activation of the bit display (negated)
with overlaid static text, exclusively via the associated
variable. This screen contains four bit display elements.
These are activated in succession via Boolean
operands
Q1
to Q4. A break contact bit logic is selected here. The bit
display is overlaid partly with static texts.
